Even back in November you could still pick up ones with that bloomin letter Q in them dirt cheap and many others for between $14-25, now since the first week of January, suddenly the market has gone absolutely nuts for them.
The question is, is this a quick flash in the pan or is this a sign of more settled growth?
Personally I think the sharp rise will even itself out by mid to late February but still continue to climb steadily until the end of the summer.
As with any investment, understanding the market forces is key here to understanding what is the driving force behind this sudden sharp rise in values across the board of LLLL.com's.
Certainly for the foreseeable future, I see good increases in prices based on many factors in the market. What worries me though is something that rises that fast, generally speaking can often come back down to earth just as swiftly, good judgement is vital here to get a good return on your domain investments.
