Your question is about the oversold character of the sector. Is -1% OS or is -1.45% OS?
In today's market, I would say like you that -1% is already oversold, but if I do a statistical study using past data - that are different from current data, then -1% could become more oversold.
I copy below the LT/ST edges figure. You can see that the ST edge has increased (as of yesterday's close). This is based on the 5D price trend and TEV pattern of GDX (the more negative TEV is the better). I also post the TEV pattern of GDX, which is today more negative than even at the close of yesterday. This means that the probability of a bounce tomorrow is high. However, the Bounce could easily fail. So caution is warranted here.

PS: I did some calculation over the week-end and found out that since 2010, we had a 0.7 correlation between that sort of oversold TEV pattern and a 3% 10 days return on GDX. That is big, but since the stat sample is small, I decided not to publish.
