Bajaj Auto Ltd. (BAJAJ-AUTO) plunged -7.6% to ₹10,045.00 with 4 signals firing. Here is what the exchange data shows.

Bajaj Auto shares closed the session at ₹10,045, down 7.62% from the previous close of ₹10,874, on a day when the Nifty slipped 0.88%. The stock opened 1.59% lower and never got back to the prior close: the session high was ₹10,714, and selling took it as low as ₹9,900. Most of the damage came after the opening gap, not in it.

Trading was unusually heavy, though the pack gives two different measures. A live signal flagged a volume spike of 17.1x, while the technicals block puts relative volume, today's volume against its usual level, at 7.65. The pack does not say how either is computed, so the gap cannot be resolved here; both point to participation well above normal.

The futures picture is stale. The F&O classification is long buildup, meaning fresh futures positions opened as the price rose, but that label is stamped to the previous close, when open interest rose 3.4% against a 0.4% price gain. It describes positioning going into this session, not the reaction to the drop.

Nothing in the deal or filing data points to institutional or insider selling. No bulk or block deals were recorded today, and there are no insider filings in the last 60 days. The only deal on file is from 4 August, when promoter entity Aryaman Family Trust sold shares worth ₹29 crore and Bachhraj & Co Private Limited bought the same value that day. The legs offset each other and read as a transfer between holders, with no visible link to this session.

The stock is below both its 50-day and 200-day moving averages, and its 14-day RSI, a momentum gauge where readings under 30 are conventionally called oversold, stood at 21.3. It has lost more than 10% over the past week and more than 17% over the past month, leaving it 19.45% below its 52-week high. The pack does not say whether these readings include today's close. A month ago, a Business Standard headline reported the stock up 3% and trading near a record high.

The one fresh news item is the most direct explanation on offer. A headline from NDTV Profit, published about five hours before the snapshot, attributed a fall of over 7% to weak domestic two-wheeler sales in September. The pack does not carry the sales numbers, so the size of any shortfall cannot be checked. Older headlines include a Univest preview of Q2 results, which the pack dates to 15 October, and two items from 56 days ago about Dhoot Transmission and EV maker River rather than Bajaj Auto.

What the data establishes is a sharp, heavy-volume decline that far outpaced a weaker market, on the day a report tied it to September domestic sales. What it does not establish is the sales figures themselves, how futures traders positioned during the fall, or whether institutions were sellers.
