Follow below technique in which populate your SelectList from your controller. Its simple and clean:

Model

public string KeywordOptionsSelected { get; set; }
public SelectList KeywordOptions { get; set; }

Controller

model.KeywordOptions = new SelectList(new List { 
                        new SelectListItem { Value = "TEST 1", Text = "Market Cap" },
                        new SelectListItem { Value = "TEST 2", Text = "Revenue" },
                        }, "Value", "Text");

View

@Html.DropDownListFor(model => model.KeywordOptionsSelected, Model.KeywordOptions, "--Select Option--", new { @id = "Dropdown_TEST" })

In this way, the code is easy to understand and View is also clean as all SelectList will be populated from cs.

You can make it more cleaner by populating SelectLists separately in methods and call in model.KeywordOptions to populate it.

public static List GetKeywords()
{
    var keyword = new List();
    keyword.Add(new SelectListItem { Value = "TEST 1", Text = "Market Cap" });
    keyword.Add(new SelectListItem { Value = "TEST 2", Text = "Revenue" });
    return keyword;
}
model.KeywordOptions = new SelectList(GetKeywords(), "Value", "Text");
