Why is MDB stock moving today? MongoDB closed at $304.59 on November 5, 2026, down 7.24% on the session and 20.88% over five sessions, and our November 6 scan priced it at $313.78 with 25 days to a December 1 earnings print.

The move was not a MongoDB headline. The company's own print is December 1, so nothing MDB reported can explain the November 5 session, and the names that share that date fell just as hard: HPE dropped 11.84% that day, NTAP lost 9.75% and GTLB gave up 6.45%.

What changed on the row is what the options market is charging for the print. MDB's 14-day implied move was 20.1% in the scan we published on November 5, and it is 10.1% on November 6. That one column is the whole gap between the 91 the scanner carried yesterday and the 86 it carries today.

What the scanner row says about MongoDB

Score 86 at rank 7 of the 49 rows we scan, sector Technology, print date December 1, earnings sentiment Positive, short interest 3.4% of float, market capitalization $25.28 billion, implied volatility 95.9, and a scan price of $313.78.

Decomposed, the 86 is the full 25 points for analyst coverage, 20 points for an 80% buy-side share, 16 points for eight strong buys, 10.1 points for a 10.1% 14-day implied move, and the full 15 for a Positive sentiment reading.

Only one of those five moved. Coverage, the book, the strong-buy count and the sentiment reading are the same ones the November 5 scan carried. The implied-move column went from a capped 15 points down to 10.1, and that is where the five points went.

What moved MDB on Dec 1?

Nothing yet, and December 1, 2026 is still 25 days away. What will move MDB that day is the print, and the options market has already said how far it thinks the stock will travel.

The band around the $313.78 scan price runs from $299.06 to $328.50, which is 4.7% of room either side over three days, and the wider columns read 7.2% over seven days and 10.1% over fourteen. A 10.1% 14-day number is a cheap event for a software name this close to its print.

December 1 carries seven names in our table. MRVL is the widest event on that calendar at 17.6% over fourteen days, ASAN prices 15.7% and OKTA 14.9%, while MDB sits at the narrow end at 10.1%.

Where the last month took the price

The settled closes say one long slide with a sharp final leg. MDB closed at $360.71 on October 6 and ran as high as $393.44 on October 28.

From there it fell every session into November: $352.96 on October 30, $330.43 on November 2, $328.38 on November 4 and $304.59 on November 5. The last of those is the 7.24% drop, and it took out the low of the month in one session.

From the October 28 high close of $393.44 to the November 5 close of $304.59 is a fall of 22.6%, and getting back to the October 6 close of $360.71 would take an 18.4% rally from here.

We have not confirmed which headline moved the stock on any single session, and we are not going to claim one. The November 5 decline arrived with HPE down 11.84%, NTAP down 9.75% and GTLB down 6.45%, and that is what a sector move looks like rather than a company event.

How does MongoDB's book compare with the other December 1 names?

MDB's book is the second-strongest on that calendar by buy-side share. MRVL's 32 buys and 7 strong buys out of 44 ratings is 88.6%, CRWD's 41 bullish ratings out of 53 is 77.4%, and OKTA's 34 out of 44 is 77.3%.

MDB's own count is 32 bullish ratings out of 40, which is 80%, with not one sell rating on the name. The book is the reason the score stayed in the eighties while the price kept falling.

MRVL is the one to watch on the other side of that book. Its sentiment reading is Mixed, which is worth 7 points instead of the 15 that Positive is worth, and MRVL still scores 83.

Short interest separates them too. MDB has 3.4% of float short and OKTA 4.7%, while MRVL sits at 3.3% and CRWD at 2.4%. There is no crowded short to lean on in MDB, and there is no cheap volatility to buy behind it. ASAN, the other small software name on that date, is the crowded one at 21.0% of float.

What has to change before the December 1 print?

The implied move first, because it is the one column that moved and the one that can move again. At 10.1% the column is worth 10.1 points, and a further compression takes the score down with it. A wider premium puts those points back.

Second the price, because the marks are on the row. Our scan price is $313.78, the post-earnings target is $328.50, and the downside mark is $299.06, which is 4.7% below where the scan found it.

Third the calendar. December 1 carries seven names, and MDB is one of three software names on it with a Positive sentiment reading. MRVL and ASAN both price a wider event on the same date, so MDB is the cheapest of the three rather than the most expensive.

And one thing that is not a lever at all. The book is 40 analysts with no sell rating, so the analyst side of the trade is already decided. The only open question is how much the options market is charging for the print.

Our scan runs at 6:30 Pacific time and every figure on this page comes from it, published in full at our open data.

So why is MDB stock moving today? On the record we hold, what moved MongoDB was a 22.6% slide from the October 28 close of $393.44 to $304.59.

What will move it on December 1 is a print the options market has just marked down from 20.1% to 10.1%. The book has 40 analysts and no sells. The reader decides whether a 10.1% premium is worth paying for a score of 86.

Frequently asked questions about MongoDB

When does MongoDB report earnings?

MongoDB reports on December 1, 2026, which is 25 days after our November 6 scan. Six other names print on that date, including OKTA, CRWD and MRVL.

Is MDB a buy before the December 1 earnings report?

On the row the case is a cheap event against a clean book. A score of 86 with 40 analysts and no sell ratings is solid support, and the 10.1% 14-day implied move is the narrowest of the seven names printing that day.

Why is MDB stock down this month?

The settled closes show a 22.6% fall from the October 28 close of $393.44 to $304.59 on November 5, with a 7.24% session and a 20.88% week behind it. MDB did not report in that window, and the decline arrived alongside HPE, NTAP and GTLB.
