NST, ASX, WZR

If Wuhan coronavirus pandemic gets worse, gold price will rise further.  So if NST is sold off, I might as well buy more (not far from its low)!  Been dropping in the last two day while gold is around USD$1570 per oz.

And if the stock market has been condemning ASX's profit announcement and selling it off over the last 2 days, I can't resist topping up (very near its day low).

WZR had been hovering near its high but also dropping in the last 2 days... and so I bought more.

All these stocks are near their high but fallen over the last 2 days.  Is it wise to buy?  Perhaps I have been gutsy and foolish!
