Volatile is a word that easily sums up technology stocks this past week. Whether the extreme highs and lows are a sign of a bubble is debatable.
Nevertheless, it's just plain freaky to look at some tech companies' stocks lately, especially those belonging to IBM, Tesla and Google.

A spokesperson for the company told CNBC that these newer areas saw revenue growth of 20 percent. But for the company as a whole, Monday's Q2 earnings report was still the 13th straight quarter posting year over year revenue declines, resulting in a big drop in investor support.
Tesla's stock also took a big hit Monday, following a report that downgraded the company from "neutral" to "sell," signaling to investors that now is a good time to take their money elsewhere.
That "sell" rating was thanks to a UBS analyst who called a Bloomberg report from May "misleading." The May report had gotten investors excited about Tesla's new battery, saying the company stood to make roughly $800 million based off deposits from interested parties.
The UBS analyst also set a new price target for Tesla's stock: $210, which is a lot lower than the stock was being traded at the time.
On the bright side, Google's stock is up — way, way up. In one day, after reporting Google's Q2 earnings, share prices jumped about 16.3 percent. The Wall Street Journal reported, "The increase was the second largest ever for a Nasdaq stock."
Two days prior to the earnings report, The Journal wrote a story explaining how the company was curbing its spending and hiring in an attempt to grow its core business and spend less time on "moonshots."

That risk is evident in a graphic produced by The Information. See those two dips in the red line around 1999 and 2014? Those represent tech companies going public while not turning a profit.
Some experts point to graphs like that to claim we're in the middle of another tech bubble, which could burst right as the U.S. is finally recovering from a recession.
