The best investors I know are boring. Here’s why.
Replying to @omar_on_sec
Boring is a strategy. My most boring holding is the one I never have to think about.

Questions
Which stocks does it cover?
US-listed companies that file with the SEC. You can add funds and stocks listed elsewhere too, but they get no filing alerts yet.
Will it sound like me?
It learns from your posts on X and from your edits to its drafts. With fewer than about 70 posts, it starts from a clear house style. You can change your style any time in Penwell’s settings for your voice.
Will my X account get in trouble?
Nothing goes out until you approve it, now or at a time you pick. Replies go out one at a time from your own browser, and there is no hands-off mode, no auto-DMs and no mass replying. X can still act on any account, and Penwell can’t promise it won’t.
Do I need Chrome?
For replies, yes, on a computer: they go out from your own browser, one at a time, after you click. Drafts, alerts and scheduling work on any phone or browser.
Can I try it before paying?
There’s no free trial, and no card until you pick a plan. You see your first post free, written in your voice, before you pick one. In your first 14 days you can cancel for a refund of what you haven’t used. If a friend invites you, your first 30 days are free.
Can I cancel any time?
Yes, from Settings. You keep the plan until the period ends, and in your first 14 days you can cancel for a refund of what you haven’t used.
