The day, step by step

Before the open

EXYN closed at $1.58 on August 20. The day before it had traded between $1.50 and $2.07. The only news in the data is from that day: at 7:38 a.m. on August 20, the company announced a new interim CEO and a new chairman. There was no news on the 21st.

The first trade on the 21st was $1.64 at 4:00 a.m., on 1,000 shares. Pre-market was thin. Only 7,991 shares traded before the bell, about 0.1% of the 7.95 million share float. The pre-market high was $1.75 at 7:21 a.m., and the stock spent most of the morning between $1.60 and $1.70.

The open and the bid at $1.52

It opened at $1.65, up 4% from the previous close. It poked up to $1.73 at 9:31, then slid.

From 9:30 a.m. on, the Level 2 book showed a large bid at exactly $1.52. The bid peaked at 50,201 shares, about 0.6% of the float, right at the open. As the price slid, it was falling toward that bid. It reached $1.61 at 9:36 and $1.55 at 9:43.

Stop It's 9:43. EXYN is at $1.55, down from $1.72 eleven minutes ago. A large bid has been sitting at $1.52 since the open. Would you buy here?
