Bless you Goldman Sachs for finally calling a spade a spade on Tesla, Inc.  (TSLA) - Get Report .

After Tesla showed that it doesn't deserve the trust of investors by doing a data dump on July 3 evening (see below tweet...), Goldman Sachs is out with a note Wednesday that needed to be written three months ago. As TheStreetreported, Goldman Sachs Analyst David Tamberrino reiterated a "sell" rating for Tesla, citing slowing sales growth of the company's electric cars currently on the market.

Tamberrino lowered his six-month price target to $180 from $190, which is 49% downside from Monday's close.

"We see potential for downside as the Model 3 launch curve undershoots the company's production targets," Tamberrino said. "This comes as demand for Tesla's established products (Model S and Model X) appears to be plateauing slightly below 100k annual run rate."

The bottom line is this: unless Tesla and Elon Musk has found the cure for the common cold -- where the cure is sprayed on people while sitting in their Tesla -- the company in no way deserves its valuation. Not only are its sales slowing, per Goldman's analysis, but there is a wave of strong electric cars coming to market over the next five years that could inhibit Tesla's gains. And from an outsider's perspective, one has to question Musk's leadership style -- ever listen to him on an earnings call? Give it a whirl, and then take a look at what the company did on Monday.

Wake up people, Tesla has proven very little besides it could make a cool electric car. This is unlikely the second coming of Ford Motor  (F) - Get Report .

Microsoft on the clock: With speculation swirling of impending layoffs, TheStreettakes a look back at how Microsoft Corp.  (MSFT) - Get Report CEO Satya Nadella has reshaped the tech giant.
