Top insider trades (Thu, May 29)

Good morning!

I sifted through 208 insider trades and calculated the best ones. Sorry for the delay, I was trying to update some code for the Aggregate Purchases / Sales and finally figured it out, but now I have to refresh all of the data which will take a little while. So I’m excluding those sections today and they will be back tomorrow.

I found:

  • HYLN is up 35% after we found two top purchases yesterday

  • Chief Accounting Officer at SNOW with 16% 3m returns sells $1M of the stock (CFO also sold $82M)

  • General Counsel at ATEN with 24% 3m returns sells the stock

  • COO at MCY buys $900k of the stock

  • Another $5M purchase at VSTS which puts the total above $11M in the last 30 days

  • A director buys $4M of KKR (his first ever purchase)

  • CTO at APP sells $29M of the stock (pushing the total sales of APP to over $400M in the last 30 days)

  • COO at DASH sells $13M

  • and much more…

Have a great day!

HYLN is already up 35% in one day (!) since we found the CFO and CCO with 50% 3m returns making Top Insider Purchases in yesterday’s CEO Watcher Premium email.

It opened at $1.24 and is up to $1.68 (+35%).

New 3-Point Purchases

3-point purchases are the highest-rated insider purchases. To qualify: 1) the insider has killer returns on previous purchases, 2) they have multiple previous purchases with great returns, 3) they have a great win rate, 4) the purchase is sizable, and 5) the purchase is not pre-planned (DRIP, ESPP, etc).

Buying the dip (stock was down -34.59% in the three months before the purchase)
