In the premium section does your list currently import sales volumes as well as prices for the recent time period? Would it be possible currently to sort the list by sales volume? Ok, this is good @EbaySeller. This gives me some nice ideas for improving the feature. I do currently note the total, rolling sales volume (that was in the chart I pasted at top of thread), but, your idea to sort by sales volume would be really handy. The info is all there in the database. At the very least, for starters I should note which issues have recent contributing sales and how many. Sorting would be fantastic. Of course all the sales data is available if users drill around the site, but it should be right there next to the issue on the stock index listing. Thanks, great idea. I will have at least some form of this live with the next site update.

I'll have to think about this one a bit @vacaboca. There are circumstances that might skew the data. For example, major auction events like a Heritage Signature Auction. I might capture 100 sales for index members in a single event which occurs only a few times a year. I think, however, it's still a great point - if you have potentially interesting data, just present it. If something looks odd, let people discuss it, figure it out, there must be a reason for it. I always say outliers are either something really interesting, or something I'm doing wrong.

A funny aside (for me anyway, I'm always entertaining myself). When I see "Signature Auction" it reminds me how the 1st comic auction or grading service will come up with a term, then the followers will have to come up with a similar term, but it's never as good.

1st: Heritage -> Signature Auction
Some thought went into that. One def: "a distinctive product by which someone can be identified"
Later: ComicLink -> Focused Auction (huh?)

1st: CGC -> Universal Grade
Later: PGX -> World Grade (really?)

Thanks, great idea. I will have at least some form of this live with the next site update @TommyJasmin Glad you agree. Once you can sort by both volume and price it will be easy to create comparable traunches to measure over time. For example maybe I would want to follow the 10 highest sales volume books under $100. Or want to compare quarterly growth for the highest volume 50 books vs the lowest volume 50 books. Or maybe I would want to do that same comparison in a specific price range. The opportunities to group and compare really can get quite interesting once liquidity information is available. That would be something I would be interested in.

I always say outliers are either something really interesting, or something I'm doing wrong. Agreed... it's been a long time since economics classes, but my thinking is that simple supply-and-demand isn't that easy here, as the market for collectible comics (generally and for specific issues) isn't elastic, or at least equally elastic. I could be wrong, but in any event I think having the additional data is useful, as you noted. EDIT - it's also fine to track volume at a less granular level - e.g., for a year... the idea is to have that info in the overall economic cycle/recession analysis.

If you're in a recession, it's likely that unemployment is up, people will likely spend less, so who is buying that keeps the price high. I would expect more dips during less optimal times, the same as any market, as more people are looking to move that Spidey 300... If volume is up then price usually comes down accordingly. I'd love to read more into this side of the hobby. @Terry88 - hey, 27 is not bad! Now, your point about tracking with the recession, yes, that was what I expected to see, a reasonable correlation. Interestingly, in my most recent market report, I touch on the same irony regarding ASM 300 you brought up! We've got high unemployment, yet books like that are going gangbusters. Check out the eBay link I used in the 1st paragraph. I can't say I fully understand it, and the explanations posed here are all plausible.
