4 top stock trades for Tuesday: AAPL, PYPL, TWTR, CSCO

With the way it's moving now, we are still looking for a potential push up to the $188 to $194 area as the next upside target. That's where several key extension levels come into play from several important ranges.

If and when Apple gets there, we'll need to re-evaluate the stock. On the downside, I'd love to see the $180 to $182 area become support, but we may need a stronger breakout for that to happen.

Until then, though, let's see that the 10-day and 21-day moving averages continue to act as support.

Specifically, I'm looking to see if PayPal can go monthly-up over $197.69, following a doji candle in December (showing some indecision) and after a slight dip below the November low.

Was that the bottom? That's the hope.

A monthly-up rotation could be a quick opportunity to snag a nice move in the stock with limited risk. If it can't rotate over this level, keep an eye on the $179 to $180. A move below that zone could put $175 or lower on deck.

That's not great, especially with the market near all-time highs. On the flip side, uptrend support is holding…for now.

If this trend line breaks (blue line), then a dip down to $41 could be in the cards.

On the upside, however, a breakout over $45 puts the 50-day moving average and the December high near $48 in play.

The stock had a major run-up from $41 in November to more than $64 last week. Now dipping to the 10-day moving average, Cisco stock is bouncing.

From here, let's see if Cisco can bounce back to the recent high near $64. Above $64 could put the 161.8% extension near $66 in play.

On the downside, though, be on the lookout for a break below last week's low, at $62.28. That could put the prior breakout area in play near $60.50, along with the 21-day moving average.
