As we discussed privately, and I may be mistaken, I thought some of those letters weren’t premium. Like r p f ? Thanks.
quick recap of the last 15 years or so:
1) the short domain sector, like all human endeavors, is prone to segmentation and rationalization. some arguments are true but others are just people trying to get sense out of things and then an idea gets mainstream and becomes a fact.
2) there is actually a pattern of good and bad letters, and even for their position on a short domain name, confirmed thru analyses of what domains sold and/or got developed by end-users. this analyses shows that a subset of the 25 Latin letters is more prone to be used by an end-user simply because most businesses target the English language and more businesses belong to highly developed nations with strong purchasing power like USA, UK, Germany, France, etc, and so there are letters that start more common words in this(ese) language(s). this subset was named "premium (western) letters" and consists of letters abcdefgilmnoprst, where letters jku and maybe vw are usually considered semi-premium and qxyz are consider bad letters (because not many businesses have names started with these letters or usually the ones that pay more use names with premium letters)
3) fast forward to end of 2013 and then a pattern started to arise where what used to be called bad letters started to got picked by Chinese. the rationale behind this is, contrary in some way to what is the pattern in the "western" world and languages, with Chinese/Mandarin there are lots of words that start with the bad letters qxyz. given that China has a lot of people and growing purchase power and that many chinese domainers entered the market at this time, this idea got pervasive until it reached a mania status in 2015 where the letters bcdfghjklmnpqrstxyz were considered premium to Chinese and coined by one namepros member as CHIPS (chinese premiums). this turned the market upside down and what was until then considered inferior quality letters and domains started to attract more money than the proven track record of the western premium letters. this even spread to numeric domains.
4) after the peak in Nov/Dec 2015 the all short domain segment got crushed in the following 2 years, and has actually hit new lows in the last month.
so when you see domains being sold for $1k or close they are not that really high, considering where they were 2 years ago. actually the market has sank +50%. strangely, the numeric sub-sector, that has even less developed sites, has been hit less, go figure.
