Samsung SDI held up pretty well today

Samsung SDI caught my eye today as it slipped to the 580,000 won range during intraday trading but managed to close above 610,000 won.

Lately, the secondary battery sector has been a total roller coaster, hot one day and cold the next. But days like today, where it bottoms out and bounces back up, always grab my attention.

However, rather than buying on the rise, I think wait-and-see buying after confirmation is the way to go for this one. If it dips below 600,000 won again, the sentiment could turn cold pretty quickly.
