Tesla Inc (NASDAQ:TSLA) made company history this month when its shares broke $300, but it looks as though it’s exhausted momentum.

Although the stock, for the most part, sustained $300 from April 4 onward, shares dipped below the benchmark Wednesday afternoon and continued downward to close at $296.44.

In the past, shares generally peaked in the mid-$200s, with the last four years seeing selloffs at $246.41, $279.20, $280.02, $254.51 and $272.23.

A Last-Ditch Effort

Around the same time the stock dipped, CEO Elon Musk tweeted survey results favoring Tesla.

Previously, Musk’s rare online activity was enough to lend the stock a boost, but this effort — or perhaps coincidental timing — did little to reverse the plunge.
