It's been the third day in a row of gains for the S&P/ASX 200 Index (ASX: XJO), as of this Wednesday's close.

After recording rises over both Monday and Tuesday's sessions, the ASX 200 tripled up with a lift of 0.31% today. That puts the index at 7,848.5 points.

This happy hump day display follows a more tentative Tuesday up on the US markets overnight.

The Dow Jones Industrial Average Index (DJX: .DJI) recovered from a sharp dip to post a small loss of 0.023%.

However, things were happier on the Nasdaq Composite Index (NASDAQ: .IXIC), which managed to climb 0.32%.

But returning to the ASX now, and it's time for a checkup on how the various ASX sectors were moving today.

Despite the market's good mood, there were still a few corners that weren't feeling the love this Wednesday.

The most obvious of those was the tech sector. The S&P/ASX 200 Information Technology Index (ASX: XIJ) had a horrible time of it, sinking by 1.2% by the closing bell.

Gold stocks also had a day to forget. The All Ordinaries Gold Index (ASX: XGD) retreated by a meaningful 0.73% today.

Another losing group were financial shares, with the S&P/ASX 200 Financials Index (ASX: XFJ) recording a 0.39% loss.

Energy stocks copped it as well, as you can see from the S&P/ASX 200 Energy Index (ASX: XEJ)'s 0.37% drop.

But that's it for the losers. Turning now to the winners, and it was real estate investment trusts (REITs) that came out on top. The S&P/ASX 200 A-REIT Index (ASX: XPJ) led the charge higher, surging by 1.17%.

Healthcare stocks got the silver medal, though. The S&P/ASX 200 Healthcare Index (ASX: XHJ) bounced 1.03% this Wednesday.

Mining shares fared well, too, illustrated by the S&P/ASX 200 Materials Index (ASX: XMJ)'s 0.85% pop.

As did industrial stocks. The S&P/ASX 200 Industrials Index (ASX: XNJ) ended up soaring 0.76%.

Utilities shares were right behind that, with the S&P/ASX 200 Utilities Index (ASX: XUJ) lifting by 0.69%.

Communications stocks enjoyed a strong day, too. The S&P/ASX 200 Communication Services Index (ASX: XTJ) got a 0.58% bump by the end of the day.

Consumer discretionary shares got an invite to the party as well. The S&P/ASX 200 Consumer Discretionary Index (ASX: XDJ) received a 0.39% upgrade.

Last up, we have consumer staples stocks. The S&P/ASX 200 Consumer Staples Index (ASX: XSJ) still got a decent rise today, inching 0.1% higher.

Taking out today's pole position was miner Stanmore Resources Ltd (ASX: SMR).

Stanmore shares shot up by a pleasing 6.31% today to $3.0 each. That was despite any fresh news or announcements out of the company.
