As previously reported, Morgan Stanley upgraded Arista Networks to Overweight from Equal Weight, with James Faucette titling his note to investors "Eating Humble Pie: Back to OW." Faucette had downgraded Arista Networks to Equal Weight on December 5 of last year, citing Arista's valuation. However, he now expects meaningful contribution from 400G products in 2019, which is more than a year sooner than his previous assumption. Also, Arista's software development gives it a sustained time to market advantage that has led to additional share gains in 100G sales, he tells investors. Faucette raised his price target on Arista shares to $210 from $125.
