3 top stock trades for Monday: MU, LCID, COST

While the stock finally broke to new all-time highs (with the prior high coming into play at $97.50 from the year 2000), Micron has pulled back recently.

Shares are testing down into the 10-day moving average, giving bulls a dip-buying opportunity. Starting Monday, investors who are long or looking to get long can consider inching their stop-loss up to this week's low.

On the downside, though, a break below this week's low could ultimately put $92 in play, then the 21-day moving average.

On the downside, $40 is a key level, along with the 10-day and 21-day moving averages. A break back below those marks puts $36 back in play.

On the upside, however, a move over this week's high (so Friday's high) could open the door to the 61.8% retracement of the current range, up near $48 to $49.

That level coincided with the 50-day moving average and the stock was a relative strength leader until this week (where it technically declined all five days). However, two of those daily losses were less than 0.2% and three of them were less than 0.5%.

In any regard, the relative strength combined with the level of interest at $536 and the 50-day moving average made Costco a buy today.

We got a decent bounce out of it, but bulls are obviously looking for more. If they get it, $550-plus is in play, with the 10-day and 21-day moving averages on the table above that.

On the downside, a break of Friday's low and a failure to reclaim it should have bulls cautious and/or potentially stopping out of their long position (depending on their trading objective and risk tolerance).
