Moderna's vaccine data leaked two days early. On Hyperliquid, the biggest short made $377K and the biggest long flipped short

News · · CryptoAnimon · All posts

Moderna's stock perpetual on Hyperliquid (xyz:MRNA) fell 20.7% on Oct 22, from 245.64 to 195.26, and traded $92.2M — 5.2 times its normal day. The low was 180.60.

The trigger came two days early. Moderna and Merck's Phase 3 melanoma results were due at the ESMO Congress on Saturday. Instead, according to Bloomberg, the figures appeared on a medical news site on Thursday around 12:30 p.m. New York time (16:30 UTC) and were taken down soon after. The headline number, reported by CNN: the vaccine plus Keytruda cut the risk of the cancer returning or death by 42% versus Keytruda alone. That is roughly what the market already expected; BioPharma Dive notes the earlier Phase 2b trial showed 44%. Moderna's stock had risen more than fivefold this year. It was a classic "sell the news."

The price drifts from about 248 down to 222 during Thursday, then drops to a low of 180.60 within two hours after 16:30 UTC, when the trial data appeared online, and recovers to about 203. Lines mark 0x325e's $2.95M short at 244.81 and 0xfe7c's $2.5M long at 247.94.

On Hyperliquid the slide started before the leak: MRNA slipped from about 241 to 222 between 13:00 and 16:00 UTC. In the first 30 minutes after 16:30, $16.2M traded and the price fell to about 197.

The shorts were right. The one who held the long cut it into the hole, then turned around and shorted the bottom of the move: 0xfe7c's new short was opened within about $8 of the day's low.

Liquidations stayed small — $341K for the whole day — because the biggest leveraged long had been selling since 08:00 UTC.
