Adobe Systems Incorporated (NASDAQ:ADBE) shares are trading lower by $1.75 at $136.30 in Monday's session. That loss comes on top of Friday's loss of $4.58 ($142.63 to $138.05).

One reason for the continued weakness in the issue may be the downgrade it received before the open. That came from Pivot Research, who lowered its rating from Hold to Sell.

After a much lower open, Adobe's stock continued in the direction before finally finding a bottom at $131.20 and began to rebound. That low comes in just above its May 18 low of $130.82.

The sharp rebound off that low has taken the stock to $136.70, which is still well shy of Friday's close of $138.05.
