I'm obviously biased because I have a position in MML, however I'm not sure companies like this are being unnecessarily hyped on HC - they just offer compelling value at these valuations - which gets people excited.
Many ASX gold miners people are talking about aren't even "exploration species" that people on HC have ramped in the past they are actually companies whose stock prices are so unloved that with their stable/growing operations (like MML) coupled with a rising PoG they are beginning to throw off crazy amounts of cash relative to their market caps.
So it's very easy to see why people are getting excited about these stocks and why they are rising so rapidly.
It would be easy to look at MML having gone up 100% in the last 2 months and think, it's already popped, but given that the PoG has also gone up nearly 20% in the last two months I tend to think this is still the VERY early stages of the rally.
