Wow another big fish with over ~7K shares (my math isn't my strong subject)? Seems to be some big time holders on TMC.Ah. Short term call plays, very tricky.
See, I bought 200 shares of stock which I intend to hold long-term: I'm an accumulator of TSLA and will be until at least 2019, so it's a question of "accumulate" or "wait to accumulate". (I also sold some $400 puts but they don't expire until November; we'll see how they turn out, but I'm actually hoping to get assigned.) So basically I just missed out on buying the same amont of stock for $6000 less. I should clarify that this purchase increased my overall position by less than 3%, and all my other lots are still deeply "in the green".
I don't particularly regret it -- I'm sleeping better having a slightly larger position going into next year. But I do have to remember in future that if part of my brain is saying "No, really, this feels like a local top, you'll probably have a better buying opportunity next week", that part is probably right. It was saying this when I bought at $279 in late 2014 out of FOMO, too, so it's sent the right signal twice, but I listened to a different part of my brain. Lesson for the future. It also said this at the last $380 top and I got that one right, buying at the bottom of the next dip.
I'm still shy of 1K.
