Not really.
Trading on a major stock exchange does not automatically give a company a large retail investor following. The marketing still has to be done. This is why companies spend time and money getting on MSNBC or FOX Business.
Here are some things you should be thinking about to gain retail investors and market support post IPO:
Keep Telling Your Story
Just because you accomplished a successful IPO does not mean you are done telling your story. Keep potential investors and current investor informed and up to date.
Establish Relationships
Establishing relationships with key industry players is an important step in gaining market support. Contact potential investors and industry leaders and introduce yourself and your company. Offer to meet with them in person or via Skype and use this opportunity to explain why your stock is worth investing in.
Have a Strong Marketing Plan
Whether you are going to allocated a big marketing budget or have an organic strategy, a marketing plan should be executed post IPO. Social media is a great way to reach potential investors and build market support for your shares. Consider creating investor relations profiles on popular platforms such as Twitter, Facebook, and LinkedIn, and use them to get the word out about your stock. Be sure to include compelling content, such as statistics and quotes from industry experts, to engage with investors and build trust.
Engage with a Market Maker
Do not leave liquidity and your stock price to chance. Have a plan to buy shares back if they get too low and a market maker to keep a strong bid and ask spread.

Get in Front of Retail Investors
Retail investors can be found online on financial blogs, twitter and chat rooms. Get in front of them. More traditional methods like TV, magazines and newspapers should also be considered if the marketing budget allows.
Participate in Events
Participating in events is a great way to generate interest in your stock. Attend networking events, industry conferences, and investor meetups to introduce yourself and your company. You can also use these events to connect with potential investors and industry professionals.
By following these steps, you can gain market support for your shares and increase the value of your company. Develop a comprehensive marketing plan, leverage social media, establish relationships with potential investors, participate in events, and focus on customer service. With the right strategy, you can boost your market presence and increase the value of your stock.
