SimNation Stock Market

Sims aged Young Adult and older can now invest in the SimNation Stock Market (SNSM) on their computer, smart phone, or tablet under the new “Investing…” pie menu path. From there, your sim can either “Research Stocks” or jump straight into the market and “Invest In Stocks…”.

Sims can invest four different amounts of money: §1000, §2000, §5000, and §10000. As the amount of money increases, so does the risk of losing money on your initial investment.

Investing §1,000 has a 25% risk, investing §2,000 has a 30% risk, investing §5,000 has a 35% risk, and investing §10,000 has a 40% risk.

Every investment has the opportunity to produce returns from 101% up to 250%, or lose anywhere from 0.01% to 100% of the initial investment amount.

Sims will receive a return on their investment in 2 days. They cannot invest again until they get their return.

Certain traits can either increase or decrease your chance of risk by 5% when investing (note: this value stacks the more traits your sim has):

Increased Chance Traits - Unlucky, Loser, and Absent-Minded

Decreased Chance Traits - Lucky, Genius, and Born Salesperson

Sims with the Frugal trait cannot research or invest in the SimNation Stock Market.

Sims employed in the Business career at Level 5 or greater will gain or lose work performance (tunable) depending on the outcome of their investments.
