Today's biggest winners and losers in the stock market.

On this episode of Stock Movers:

- Coinbase (COIN) was among the best performers in the S&P 500 in trading on Friday. Cryptocurrency-linked stocks, including Coinbase are extending gains on as Bitcoin passed the $80,000 level. The sector also got a boost on Thursday after the SEC greenlit digital versions of securities to start trading in the US.

- Netflix (NFLX) received its first bearish analyst rating in months on Friday, after Wells Fargo Securities downgraded the streaming-video company to underweight, citing concerns about user engagement. Analyst Steven Cahall wrote that Netflix "has lacked big original series and it's showing" and that "breakout hits" are necessary for the stock to work again.

- Nucor (NUE) shares down 5.7% after the steel producer’s third-quarter earnings-per-share forecast missed the average analyst estimate. Analysts note that the forecast might prove to be conservative.
