Even though Goldman Sachs (GS 0.22%) has been around for almost a century and a half, it's still new to the investing public, choosing to stay private until its belated IPO in 1999. Institutional investors have nevertheless poured into Goldman Sachs stock over the past 16 years, fueling a 230% total return compared to the S&P 500's 114%.

Which institutional investors have benefited from Goldman's ascent? The answer can be found in the slideshow below, which reveals the five biggest owners of Goldman Sachs common stock right now -- as a side note, it's worth noting that Berkshire Hathaway (BRK.A 1.18%) (BRK.B 1.30%) announced this morning that it reduced its position in Goldman's stock (revealed in the slideshow) by 13% last quarter. The Warren Buffett-led Berkshire Hathaway now owns approximately 2.6% of Goldman's outstanding shares.

One point in the slideshow that's worth noting is how much smaller Goldman Sachs' biggest shareholder is compared to rival investment bank Morgan Stanley (MS 0.44%).

Conversely, Morgan Stanley's biggest shareholder, a Japanese financial company, owns 22% of the illustrious Wall Street firm.
