In recent couple weeks I've been participating in buying 4L .com portfolios for 6-figures. Managing several hundreds of 4L now (non-Chinese, with aeiouv) on behalf of clients, I don't practice "a'la commodity trading" or "Chinese trading" at all.
For all 4L owners I'd suggest to get back to the roots of domaining, ie. don't sell for a minimum, don't sell in auctions, offer 4L in the way like generic domain names are offered. Has anyone here sent a quote on $300 to a random generic domain name, replying to incoming inquiry? - I don't think so
4L .coms are fantastic names for brands, either startups or existing companies which can upgrade eg. their 4-words to a 4-letter name & domain name. Great opportunity for branding, re-branding, general marketing.
Not everyone knows also that ticker symbols of publicly listed companies consist of 4-letters mostly (see GDDY and GDDY.com)
Generally I'd say that 4L means relatively low-risk domain investing, eg. comparing to generic names. Most of buyers easily accepts prices in range $1k~$2k, regardless of quality of a domain name. It's simply a "reasonable expense" in people's perception. So with 4L prices at current level, it doesn't seem difficult to produce positive ROI in middle-to-long-term. It's great time for purchasing. ~AW
