No problem. It's a common mistake to think that institutions are long-term, steady holders. This is based on 1950s patterns, when "instituitions" were staid banks, insurance companies, and pension fund managers with a long time horizon.
But when you look at it, all the financial institutions are full of short-term day-trader types. The financial institutions counted in "institutional holdings" these days include the brokerages, who literally hold stock in inventory so they can sell it and lend it; they include the market makers, who do the same thing; they include the options market makers; the options exchanges; they include quants like Rennaissance Technologies; they include most of the major short-term-trading hedge funds and mutual funds; etc. All the proprietary traders are included in those institutional numbers!
I actually think that the "retail holders" are probably mostly long-term, steady holders, though I am sure there are some swing traders in there. Because honestly, if you were an individual or private trust or charity or private business, and *not* a financial institution, why would you be speculating on short-term swings in Tesla stock? That's more the sort of thing the traders employed by financial institutions do.
The way "institutional holdings" are reported, the remaining "retail holders" include the Saudi Public Investment Fund and Tencent. Who knows what other similar organizations are in the "non-institutional holders" category but have <5% and aren't required to report? I tend to think the "non-institutional holders" are probably much longer-term investors, on average, than the "institutional holders".
A while ago I attempted to sort the long-term institutional holders from the short-term institutional holders. Bailie Gifford, who represents the Scottish Mortgage Trust, is an old-fashioned long-term institutional holder. Rennaissance Technologies is the exact opposite. Most of the others are somewhere in between.
