Being added to the S&P/ASX 200 Index (ASX: XJO) is no small feat.
Outside of reflecting a company's strong performance, it also opens up a new universe of institutional investors and ETFs to the company.
Index inclusion can also shine a light on compelling businesses that the broader market has been sleeping on.
Here are three newly added ASX 200 members worth adding to your watchlist.

SRG Global (ASX: SRG)
SRG is a Perth-based infrastructure services company employing more than 5,000 people across more than 20 industries, with revenues approaching $1.6 billion.
What sets it apart from your typical contractor is how recurring its revenue is, with more than 80% of the business tied to annuity-like streams.
The most recent half-year results told a good story: EBITDA climbed 20% year on year, and the work-in-hand book hit a record $4.2 billion, up 24% from the prior year.
For investors looking for infrastructure exposure without the volatility of miners and explorers, SRG is worth a closer look.
Vulcan Energy Resources (ASX: VUL)
Vulcan is building what it describes as the world's first carbon-neutral lithium operation, drawing lithium from geothermal brines beneath Germany's Upper Rhine Valley.
The flagship Lionheart Project is targeting 24,000 tonnes of lithium hydroxide per year, enough to supply batteries for around 500,000 electric vehicles annually.
As European carmakers face mounting pressure to clean up their supply chains, a domestically sourced green lithium product could stand to benefit.
Vulcan Energy has secured a €2.2 billion financing package, and construction of the project is now underway in Frankfurt.
The company is still pre-revenue, so risks remain high, and performance depends on the scale of the lithium deposits and on management execution.
But if Vulcan can execute, investors could gain a lot.
Predictive Discovery Limited (ASX: PDI)
Predictive Discovery is a leading West African gold producer and developer, listed on the ASX.
Predictive Discovery's Bankan Gold Project in Guinea has been shaping up as one of the more significant gold discoveries in West Africa in recent years.
The timing of Predictive Discovery's index promotion could hardly be better, given that the price of gold has risen significantly over the last few years.
Similar to Vulcan, future performance depends largely on the scale of the deposits found and on management's ability to execute its plan.
Despite all of this, the scale of the Bankan project gives plenty of reasons to be excited.
Foolish takeaway
Index inclusion gives investors the opportunity to analyse new stocks with exciting business models.
SRG, Vulcan, and Predictive Discovery are no exception.
All have fascinating future growth trajectories, and I reckon they should be on investors' watchlists.
