Biggest thing to watch: the price has already been rising for 87 weeks, so timing is the risk more than the business. ## What is the Protagonist Therapeutics share price today? Protagonist Therapeutics, Inc.'s share price was $135.26 at the close on 5 November 2026. It has been rising for 87 weeks. That is 14.9% above its average price over the last 200 trading days. In the last 52 weeks it traded between $80 and $155, and at that close it sat 74% of the way up from that low. Over the past 13 weeks it has done worse than the S&P 500, and it has been behind for 1 week running. Over the last 10 years the share price moved +1,069% while the S&P 500 moved +236%, so it is ahead of the index over that whole period. It was last ahead over 13 weeks in the week of 30 October 2026. The chart above shows the 13-week comparison for every week. This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row. ## What dividend does Protagonist Therapeutics pay? Protagonist Therapeutics, Inc. pays no dividend. In the last 12 reported quarters it declared no dividend per share, so there is no payout history to chart and no yield to show. Companies like this usually keep their earnings in the business, so the cash-flow sections show where that cash goes. ## Which stock lists is Protagonist Therapeutics on? Protagonist Therapeutics is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list. ## Is Protagonist Therapeutics profitable? Protagonist Therapeutics, Inc. earned ₹0.2 B of net profit in the Jun 2026 quarter. The full FY25 year was a loss of ₹0.1 B. That is 76.3% of the quarter's revenue. The same quarter a year earlier lost ₹0.03 B. 7 of the last 12 reported quarters were loss-making. For the full year, FY25 profit was −₹0.1 B (−147.3% on the year before). This company reports in its home currency, not US dollars, so the money charts are left out here. The figures in the text are in that currency (₹); nothing is converted. ## How much revenue does Protagonist Therapeutics make, and is it growing? Protagonist Therapeutics, Inc. reported ₹0.2 B of revenue in the Jun 2026 quarter, +3,749.2% on the same quarter a year earlier. That is the 2nd quarter in a row with growth on the year before. Over 4 years it has grown 13.9% a year on average. The last full year, FY25, came in at ₹0.0 B. The last four reported quarters add to ₹0.3 B. FY25 revenue was ₹0.0 B, −89.4% on the year before. Recent pace: the last four quarters grew +938.3% on average, against 13.9% a year over the longer run, so this year is growing faster than its own long-run rate. Is growth speeding up? Revenue over the last 12 months grew +34.8%, against −6.1% a year over the last 8 quarters (accelerating); profit over the last 12 months grew +59.3%, against −28.7% a year (accelerating). This company reports in its home currency, not US dollars, so the money charts are left out here. The figures in the text are in that currency (₹); nothing is converted. ## How much of its sales does Protagonist Therapeutics keep? Protagonist Therapeutics, Inc.'s sales have fallen to very little: FY25 revenue was ₹0.0 B, against ₹0.4 B in FY24. On sales that small an operating margin is not a useful reading, so this section is left out until sales recover. ## Is Protagonist Therapeutics' profit turning into cash? Protagonist Therapeutics, Inc.'s cash-flow history is too short to judge how much of its profit turns into cash. In FY25 it brought in ₹0.1 B of operating cash against −₹0.1 B of profit. After ₹0.0 B of spending on assets, ₹0.1 B was left over as free cash. Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year. What to look at next: it spends almost nothing on new assets, so the cash goes on running the business. The next section shows the spending figures. This company reports in its home currency, not US dollars, so the money charts are left out here. The figures in the text are in that currency (₹); nothing is converted. ## Where does Protagonist Therapeutics' cash go? Protagonist Therapeutics, Inc. does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent ₹0.0 B on assets over the last 3 years. Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn. Spending on assets: ₹0.0 B over the last 3 years. In short: almost nothing is being spent on new assets, so the cash goes on running the business. This company reports in its home currency, not US dollars, so the money charts are left out here. The figures in the text are in that currency (₹); nothing is converted. ## What is Protagonist Therapeutics' P/E ratio, and how does it compare with its own history? Protagonist Therapeutics, Inc.'s P/E is 110.8×, with too little history to compare. This compares the share price with the company’s own past. It does not say what the business is worth. In short: there is too little history to say whether the multiple is high or low for this company, so the earnings trend underneath matters more than the multiple. ## Is the Protagonist Therapeutics business getting better or worse? Protagonist Therapeutics, Inc.'s business trend cannot be read yet. There are fewer than eight usable quarters of growth figures, so there is not enough history to read the trend. This is based on 9 quarters of 2 measures, with some gaps. Why it matters: with too little history, we say so rather than guess a direction. The return figures here are yearly, not quarterly. They show level and direction only; they can support the growth lines but never decide the reading alone. There are fewer than eight usable quarters, so this page does not guess a direction from so little history. ## How much does Protagonist Therapeutics earn on its capital? Protagonist Therapeutics, Inc. earned a ROE of −21% in FY25. That is up from a low of −59% in FY22. Its return on capital used (ROIC) is left out: on sales this small it reads 189%, a number that says nothing useful about the business. ## Does Protagonist Therapeutics have too much debt? Protagonist Therapeutics, Inc. has total debt of ₹0.0 B against shareholder equity of ₹0.8 B as of Jun 2026, so its debt is 0.01× its equity, which is very little. Year by year, that ratio went from 0.02 in FY21 to 0.02 in FY25. So the returns on this page come from the business, not from borrowed money. This company reports in its home currency, not US dollars, so the money charts are left out here. The figures in the text are in that currency (₹); nothing is converted. ## What is the Protagonist Therapeutics shareholding pattern? 19.5% of Protagonist Therapeutics, Inc.'s tradable shares are in short positions, which are bets that the price will fall, so a large group of traders is betting against it. At normal trading volumes, closing those positions would take about 12.3 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead. It is a single reading at one point in time; we do not have its history. Why it is at this level: the figure does not say who holds the short positions or why, so we show the level without guessing the story. ## How far is Protagonist Therapeutics from balance-sheet trouble? For Protagonist Therapeutics, Inc., the Z-score is 72.22. A Z-score above about 3 is safe and below about 1.8 signals danger, so this is well clear of danger. It estimates how far the balance sheet is from trouble; it is not a forecast of failure. Why it matters: a Z-score of 72.22 is well clear of the danger zone, so the balance sheet is not the risk here. ## How does Protagonist Therapeutics rank in its industry? 49.6 out of 100, rank 15 of 30 in Biotechnology, with 74% of the evidence available. Protagonist Therapeutics, Inc. scores 49.6 out of 100 against the 30 companies it is compared with in Biotechnology, ranking 15. The evidence is balanced: no factor stands out, so another reported quarter is needed before the picture is clearer. The four parts add up to the total exactly: 22.5 + 11.8 + 6.5 + 8.8 = 49.6. This is the same number shown on the industry page; it is worked out once for the whole group and read here. What would change it: The score would fall if profit growth turns negative or margins stop improving while the share price lags its sector. ## Which companies is Protagonist Therapeutics compared with? Protagonist Therapeutics ranks 15 of 30 Biotechnology companies on the 4-Factor Sector Score, with 49.6 out of 100. 1.

Missing figures are not scored as bad. They lower the confidence and pull the final score toward the middle. Relative strength counts only when the company has a reading for this week; with no reading, that factor is left out and its 20 points are shared across the other three in proportion. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step path the industry is placed on (basing, turning, breaking out, leader, fading, asleep), read from how many weeks running it has led S&P 500 and whether that lead is growing or shrinking. It describes where the share price stands, not the direction of earnings, and it is not a recommendation; it is left blank for a company whose weekly history is too short or too stale to read. The figures in this ranking come from the industry comparison: results through the Sep 2026 quarter, and the P/E at that quarter's end. The sections above use the latest weekly price, so a P/E or return there can differ a little from the one here. The stage words in this ranking (such as losing its lead or breaking out) describe the lead over the index, not the price phase in the price section.

Protagonist Therapeutics, Inc.'s market capitalisation is $8.8 B at a stock price of $135.26. Market cap is the share price times the number of shares, so it changes whenever the price moves (as of 5 November 2026). ### How is Protagonist Therapeutics performing? Protagonist Therapeutics, Inc.'s share price has been rising for 87 weeks. Over the past 13 weeks it has done worse than the S&P 500, for 1 week running. This describes what the data did, not a rating (as of 5 November 2026). ### Will Protagonist Therapeutics's stock price go up? This page does not forecast Protagonist Therapeutics, Inc.'s stock price. What it shows instead: the stock price is $135.26, and it has been rising for 87 weeks. Nobody can reliably say which way a price will move, and this site does not try (as of 5 November 2026). ### What could break the Protagonist Therapeutics story? Biggest thing to watch: the price has already been rising for 87 weeks, so timing is the risk more than the business. On price, this page treats a rise as over when the share price closes below its 200-day average on two Fridays in a row (as of 5 November 2026). ### Is Protagonist Therapeutics a stock worth studying right now?
