Stocks closed up handily on Friday after getting close to a retest of August lows. Investors keep proving that they will buy value and dips when the stock market sells off. 24/7 Wall St. reviews dozens of analyst research reports each morning of the week to find new trading and investing ideas for its readers. While some analyst calls cover stocks to buy, a traditional Buy or Outperform rating comes with implied upside of 8% to 15% for Dow Jones Industrial Average and S&P 500 stocks.

There is another category of analyst upgrades and positive calls outside of these traditional views, and these are where an analyst sees much higher upside. Some analyst calls suggest upside of 30%, 50% or even 100%. 24/7 Wall St. ends up reviewing 200 to 300 analyst calls during the course of most weeks, and out of these reports there are some serious upside calls — and sometimes they are in stocks that are not micro-cap or very low-priced.

Investors must know that the more upside an analyst sees, the more risk is implied as well. This week’s massive upside calls did actually include some major large cap stocks that are extremely well known to the investing community and to consumers alike.

Here are seven fresh analyst calls from this past week in which analysts see massive upside, above and beyond the traditional analyst calls.

Ambarella Inc. (NASDAQ: AMBA) was maintained as Overweight by Pacific Crest on Tuesday, with the firm saying that the company should not be tied exclusively to GoPro. While the price target was cut to a more realistic $102 from $123, the firm’s lower price target still leaves more than 70% implied upside, based on other opportunities outside of GoPro.

Ambarella’s consensus analyst price target is now around $99.00, and the shares have a 52-week trading range of $33.71 to $129.19.

Devon Energy Corp. (NYSE: DVN) was raised to Outperform from Market Perform at Bernstein on Friday. The firm assigned a $58.00 price target, which was against a prior $37.09 close and versus a $40.72 close after the upgrade. This still leaves implied upside of about 45%, if you include the dividend, and that is after shares rose almost 8% on Friday.

Devon has a consensus price target of just over $60.00, and its 52-week range is $36.01 to $70.48. Devon’s market cap is still over $16 billion, despite being cut in almost half from its 52-week high.
